I had similar issues with memories, so that’s why I switched to Immich last week. So currently I still sync using Nextcloud to a specific directory and then use the read-only functionality of Immich. I also used Photoview for a period of time which also works quite nice, but the app gets updated less often than Immich’s app and also has less functionality. In the end I hope to completely move to Immich when syncing works both ways.
